Administrative data
PBT assessment: overall result
- Name:
- Dioctyl phosphonate
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Dioctyl phosphonate
- Name:
- Dioctyl phosphonate
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Related composition:
- Dioctyl phosphonate
- Reference substance:
- Dioctyl phosphonate
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to Annex XIII of the REACH Regulation (EC n. 1907/2006), a substance is PBT if it fulfills all three of the following criteria.
1) Persistence
A substance fulfills the persistence criterion (P) when:
– the half-life in marine water is higher than 60 days, or
– the half-life in fresh- or estuarine water is higher than 40 days, or
– the half-life in marine sediment is higher than 180 days, or
– the half-life in fresh or estuarine water sediment is higher than 120 days, or
– the half-life in soil is higher than 120 days.
The assessment of the persistency in the environment shall be based on available half-life data collected under the adequate conditions, which shall be described by the registrant.
2) Bioaccumulation
A substance fulfills the bioaccumulation criterion (B) when:
– the bioconcentration factor (BCF) is higher than 2000.
The assessment of bioaccumulation shall be based on measured data on bioconcentration in aquatic species. Data from freshwater as well as marine water species can be used.
3) Toxicity
A substance fulfills the toxicity criterion (T) when:
– the long-term no-observed effect concentration (NOEC) for marine or freshwater organisms is less than 0.01 mg/l, or
– the substance is classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2, or 3), or
– there is other evidence of chronic toxicity, as identified by the classifications.
The substance is ready-biodegradable and fails to fulfill persistence criteria.
The predicted log Kow for the substance is 6.13 and considering its structure and its physical-chemical properties the potential bioaccumulation of the substance can not be excluded.
The substance is not CMR and is not toxic.
Anyway the substance does not fulfill neither PBT nor vPvB criteria considering its is ready-biodegradable (90 % of biodegradation in 28 days).
